Abstract

As a complement to the coherent combination of the large 8-m VLT Unit Telescopes, the Very Large Telescope Interferometer will operate with a dedicated array of Auxiliary Telescopes (AT's). This array consists of three 1.8-m telescopes that can be relocated on thirty observing stations distributed on the top of the Paranal Observatory. The specificity of the AT requirements and design originates from its dedication to interferometric observations down to visible wavelengths. This calls for a mechanical stability at the nano-meter level together with the capability to relocate the telescope. The AT has entered into manufacturing phase in mid-1999. This paper presents the main specifications and the final design of the AT.
